Benchmarking ZFS performance is more than just running a few I/O tests—without the right methodology, results can be misleading or even completely inaccurate. Many traditional benchmarking tools and approaches fail to capture how ZFS actually works, leading to flawed comparisons and incorrect conclusions. Join us as we cut through the noise and show you how to properly measure ZFS performance, with insights from industry experts like Allan Jude and the FreeBSD/ZFS community. Whether you’re tuning ZFS for production, evaluating hardware choices, or just curious about performance, this session will help you separate real insights from misleading metrics. Your takeaways after the webinar: 1. Common mistakes in ZFS benchmarking (e.g., not accounting for the ZFS ARC, improper dataset configurations, using inappropriate tools). 2. How to design benchmarks that reflect real-world performance, including database workloads, virtualization, and high-throughput applications. 3. Why ZFS caching, compression, and copy-on-write impact benchmarks, and how to interpret results correctly. 4. Recommended tools and methodologies for meaningful performance analysis.
